JAKARTA - Indonesia's Corruption Eradication Commission (KPK) has said it will not hesitate to investigate anyone, even the younger son of President Susilo Bambang Yudhoyono, provided there is enough evidence, as the agency battled accusations that it was politically biased.

Agency spokesman Johan Budi told reporters on Friday night that “anyone can be a suspect if we find two pieces of evidence”.

His comments signal the KPK is not likely to ease up on its efforts to unearth high-level graft, even as elections for Parliament and the presidency draw closer.

Mr Johan was speaking after Mr Anas Urbaningrum, the estranged former chairman of Dr Yudhoyono’s Democratic Party, was detained over a multi-billion rupiah graft scandal.
